there is an easycruise forum & I must admit I haven't looked at it at www.bigorangeboat.com
that may provide you with more information.
Looking at reviews on a couple of british forums, it is clear that the people who went on easycruise for a few days knew exactly what to expect and seemed to be more than happy when they went.
Yes rooms are small but if you are organised they are adequate. The great thing about easycruise is that unlike on most cruises that depart early evening, easycruise leaves at about 3am so you can have a late night meal or go to a show or nightlub in the town.
